substance may present a hazard if it is poured down the drain untreated or placed in the trash. Based on these considerations, EHS recommends the following disposal procedures for ethidium bromide. * Electrophoresis Gels * Ethidium Bromide Solutions * Gloves, Equipment and Debris Electrophoresis Gels Trace amounts of ethidium bromide in gels should not pose a hazard. Higher concentrations, e.g., when the color of the gel is dark pink or red, should not be placed in laboratory trash.

Extraction is a technique used for separating a compound from a mixture. An example is separating a water-insoluble organic compound from an aqueous mixture by extracting it into a water-insoluble organic solvent. These extractions are often part of the workup procedure for isolating and purifying the product of an organic reaction. Because trace amounts of water are often present at the end of an extraction process, a drying reagent is needed to ensure a dry product. The process of liquid-liquid

issues of the case and discuss your thoughts and opinions and more importantly why you think them!!!! If you want a really basic format that works, here is one: 1. Background & key facts 2. Main Problem Statement 3. Possible Solutions and Options 4. Your Recommended Solution & Analysis (WHY) Most cases will have questions that help you to tackle the case. I suggest that you maybe even read those questions before you read the case. This should help you in getting started. I do not want you to

which the solution can be made. As the temperature increases, the particles of the solid move faster, which increases the chances that they will interact with more of the solvent particles. This results in increasing the rate at which a solution occurs. Temperature can also increase the amount of solute that can be dissolved in a solvent. Generally speaking, as the temperature is increased, more solute particles will be dissolved. For instance, when you add table sugar to water, a solution is quite

2.04 AP Practice: Part 2 10/15 total points earned. Question 1 (Worth 5 points) The boxes described below have the same volume, but different dimensions and surface area. Use this data as the basis for a discussion of beneficial cell shapes. Essay Submission When the volume is too large relative to the surface area of the cell, diffusion cannot occur at sufficiently high rates to ensure this. Therefore cells size is wanted to be relatively small. Box A's surface area to volume ratio is

The purpose of this lab was to get used to using lab machinery such as the spectrometer. Spectroscopy is the interaction of matter and electromagnetic radiation. Most of our lab was based on the idea that matter would absorb and then reflect the colors we wanted to see based on the dyes we used. We also tested how strong the dyes were by testing them on filter paper and seeing how far they would travel up the paper. During dry lab we put all the classes’ data together to get accurate absorbance averages

Define the following terms and use them in your answers below. - Solubility: The greatest quantity of a solute that can be dissolved into a solvent - Soluble: When a substance can be dissolved into a solvent. Ex: sugar can be easily dissolved into coffee or tea. - Insoluble: When a substance cannot be dissolved into a solvent. Ex: oil cannot be dissolved into water. - Hydrophilic: Describes a substance that can easily be mixed or dissolved into water. Ex: salt - Hydrophobic: Describes

background knowledge, I know that there are stomach acids in our stomach that help dissolve food, which exemplifies how this acid requires high solubility in order to whole and dissolve all the food we eat. Changing the potential hydration of an aqueous solution, “you can change the charge state of the solute” [4]. By changing the charge state of a solute, it is possible to convert molecules to having no net electrical charge and having decreased electrical charge “the solute has minimal solubility” [4]
